Worst customer service ever for an 81 year old

Tfg Customer service is kaak, they don't even care about elderly people. They sending my father in law from pillar to post. All started when I used my father in law account for online shopping. My father in law is 81 years old and has no clue about online shopping. So the account has been flagged and blocked. We were told to go to the nearest tfg store and we went the today on the 3rd June 2025. The store called their head office and he was asked questions, somehow their system went offline now the agent on the call suspected ***** and was told to go to another store and make the call there , my 81 year old in law exhausted as he was grimbling but he agreed to do so. Now at Markhams they made the call and now the agent says no he failed to answer questions correctly now he must go get 3 months bank statement and come again and make the call. Mind you my inlaw is in good standing, his account always paid in time but tfg doesn't care and treated him like he's a *****. I wonder if it's because of skin color that's why these agents don't care. I never saw such degrading behavior, not even considering that this old man is 81cant be send from left to right.
